GAS-J ET.

Specification of Letters Patent.

Patented Mar. 2?, 19117.

Application filed October 10, 1916. Serial No. 124,903.

To all whom it may concern:

Be it known that I, JAMES T. GREGORY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Imprpvementsin Gas-Jets, of which the follow is a specification.

This invention relates to gas jets.

The object of the invention is to provide a device of this character which will supply gas to a burner in predetermined quantities,

for the convenience of various occupations requiring diiferent lights of a given power.

With the above object in view the invention consists of preferably a single casting comprising a common inlet end, branch pipes of difierent diameters connecting with the inlet end, valves located in said branch pipes and a common passage end for the said branch pipes.

In the drawings:

Figure 1 is a perspective view of the invention;

Fig. 2 is a longitudinal sectional view'of the same.

In certain occupations it is sometimes desirable to employ lights of diiferent power. It is necessary and desirable to have these lights so arranged as to be easily and accurately adjusted so that the strength of the light used in a certain class of work will not vary at different times. Upon other classes of work it is desirable to have a light of a difierent intensity. The present invention contemplates a meeting of these requirements and the combining of the different lights into one burner.

With the above objects in view the invention consists of a casting having at one end an inlet 1. This inlet is preferably internally threaded so as to receive connection with a suitable source of supply. Connected with the inlet and preferably mounted thereon are branch pipes 2 and 3 of diiferent diameters, the pipe 3 being preferably Copies of this patent may be obtained for smaller than the pipe 2. Valves 5 and 6 located in these pipes are adapted to control the flow of gas therethrough. The pipes are preferably as shown of oval formation and meet at the end opposite the inlet, and converge into a common discharge end 7. This end may be provided with a slip joint to receive the end of the burner pipe 8.

F rom. the foregoing it will be apparent that the invention provides a device for controlling the gas to a single burner, the said control providing means for quickly regulating the amount of gas supplied and thereby controlling the power of the light. As the pipes 2 and 3 are of different diameters, when the valves are opened to their full capacity these pipes will always supply the same amount of gas to the burner. In the device shown the burner may be supplied from the large pipe 2 and when achange is desired it is only necessary to open the valve 6 and close the valve 5 to obtain a light of lesser brilliancy. A like operation may be repeated to restore the light to its former condition. By opening both of the valves a great quantity of gas is supplied to the burner with a proportionately increased light.

Having described the invention, what I claim is:

A gas jet comprising integral branch pipes of different diameters arranged in elliptical form and provided with a common inlet and outlet located at the ends of the ellipse, a valve casing located in each of said pipes at diametrlcally opposite points in the ellipse, valves located in each of said casings and having openings therethrough, said openings being of the same diameter as the pipes in which the valves are located and finger pieces carried by said valves, said finger pieces being disposed in opposite relation.

In testimony whereof I afiix my, signature.

JAMES T. GREGORY.
